Magnetic Field Drift
When a strong magnetic field is present then the electron mobility can be a tensor:
where the inverse of the mobility has been used because the actual expression for the electron mobility cannot be written in a compact form. The quantity
μ
dc
is the electron mobility in the absence of a magnetic field.
Convection
The convection due to a flow field (for gases and liquids) can be easily modeled by adding the flow field to the drift velocity under the electromagnetic field. In general, the flow field has negligible effect on electrons but can have significant effects on ions.
